Nanometer yellow tungsten oxide has excellent transparency (high visible light transmittance) and electrical conductivity so that it may be used to prepare near-infrared shielding material. And the prepared materials can effectively shield electronic radiation, ultraviolet light and infrared light, which are all harmful to human body. The specific operation is to make the yellow tungsten oxide nano powder into dispersion by nano-dispersion technology, and then apply it to the surface of some visible window materials, so that the conductivity of its surface can be improved without affecting the transmittance of visible light. Moreover, it can shield harmful electron radiation.
The nano grain size yellow tungsten oxide powder can also be applied to various transparent conductive, antistatic, anti-radiation coatings and electrodes to produce various heat-insulating, absorbing and reflecting infrared materials. At present, yellow tungsten oxide nanopowder is mainly used in the manufacture of liquid crystal displays, flat panel displays, plasma displays, touch screens, electronic paper, and the like. These products can be widely used in EL cold light, cold light board, LED, LCD, OLED, electronic membrane switch, antistatic additive, radiation protection coating and other fields.
